Where is the vats module

Where is the vats module and if I replace it with a used one do I have to replace the key resistance also??

VATS is in the ECM.

Yes you would have to get the resistor pellet replaced to match the value of the one you are putting in. There are some Macgyver like remedys around it, but I like to have the security. The main Macgyver trick is to pull out the ignition cylinder and rewire under your dash to a place you can reach it. The insert your key into and either A- Leave it in to bypass vats or B- remove it and insert it constantly. Oh yeah...you would go back with a regular ignition cylinder. Awright...I am going on and on here...What is the problem you are having anyhoot....

The problem I am having is I can't get the security light off. I pulled apart the connector that runs up to the locking cylinder to measure the resistance with the key in and I got no value, so I pulled the key out and measured the pellet and got what the value was supposed to be. I then made a resistor that matched the value of the key and plugged it in to the steering column and that didn't help.

I know the wires are good because when I ohm out the other side of the the connector and get a resistance from running through the VATS module. I also pulled down what I think is the VATS module (black box next to the computer in the passangers side dash) and there is a crack in the casing. (Is that the VATS module??)

I know its not the starter because I can jump the starter relay and get the car to turn over. I can also jumper the fuel pump relay to turn it on but with the VATS problem I can't get the injectors to fire.
